Aniline is a weaker base than ammonia because the lone pair on the nitrogen atom in aniline is partially delocalized into the benzene ring, making it less available for donation to form a bond with a proton. In contrast, the lone pair on the nitrogen atom in ammonia is more readily available for donation, resulting in a stronger basicity.

Why ammonia is stronger base than aniline?
Ammonia is a stronger base than aniline because the lone pair on the nitrogen in ammonia is more readily available for donation compared to the nitrogen in aniline, which is partially delocalized due to resonance. As a result, ammonia is able to more effectively accept a proton to form its conjugate acid, making it a stronger base.
Why cyclohexylamine is a stronger base than aniline?
Cyclohexylamine is a stronger base than aniline because the nitrogen atom in cyclohexylamine is less hindered by bulky substituents than in aniline. This allows for easier access of the lone pair of electrons on nitrogen in cyclohexylamine, making it more available for proton transfer. Aniline's lone pair is more delocalized into the benzene ring, which reduces its basicity.
Which is more acidic aniline or ammonia?
aniline is more acidic because in aniline a electron withdrawing benzene is connected.electron withdrawing capacity of benzene is due to its delocalizing pi electrons cloud.due the action of benzene the presence of unshared pair of electron over nitrogen is somehow decreases.which increases its acidic nature. But in case of ammonia there is no electron withdrawing group.so its unshared pair of electron remains undistrubed,which decreases its acidity and increases its basisity
Which substance has the weakest base baking soda or ammonia?
Baking soda (sodium bicarbonate) is weaker as a base compared to ammonia (NH3). Ammonia is a stronger base than baking soda because it is a more effective proton acceptor, meaning it can more readily accept and donate protons in a chemical reaction.
Why Aniline is less basic then ammonia?
Aniline is less basic than ammonia because the nitrogen lone pair on aniline is partially delocalized into the benzene ring, making it less available to accept a proton. Ammonia, on the other hand, has a more localized lone pair on nitrogen, which is more readily available for protonation.
Why aniline is weaker base than methylamine?
Since tha pka of the aniline ion is equal to 4.6, the anilinium ion is a stronger acid than the methylaminium ion, and aniline (c6h5nh2) is a weaker base than methylamine (ch3nh2).

Which is strong base aniline or o-nitroaniline?
Aniline is a stronger base than o-nitroaniline because the nitro group in o-nitroaniline is electron-withdrawing and decreases its basicity compared to aniline. In basicity trends for amines and anilines, the presence of electron-withdrawing groups decreases basicity.
Is ammonia a stronger base than water?
Yes. Ammonia has a pKb of 4.75. Water has a pKb of 13.995.
Why is ethanoic acid a stronger acid in liquid ammonia than in aqueous solution?
Ethanoic acid is a stronger acid in liquid ammonia because ammonia is a weaker base compared to water. Therefore, in liquid ammonia, ethanoic acid easily donates a proton to the ammonia molecules, forming the acetate ion. This proton transfer reaction is more favorable than in water due to the difference in the basicity of the solvent.
Why is aniline weak base?
The amine lone pair in aniline is conjugated to the benzene ring. Amines are strongly electron donating, so the lone pair is partially "stuck" in the aromatic system. This means that it is less available to latch onto a proton (the definition of basicity).
Which is more basic cyclohexyl aniline or aniline?
Strength of bases is related to the ease of accepting a proton which inturn depends on the availability of electron pair on the nitrogen atom (or some other basic atom). More is the availability of electron pair, more easily the proton will be accepted and more will be the basic strength.Aniline is a weaker base than ammonia or cyclohexylamine. It is because of the fact that the electron pair on nitrogen is involved in delocalization, making it less available for donation.
Why cyclohexyl amine is stronger than aniline?
in the case of aniline, the lone pair on nitrogen is involved in resonance with the benzene ring, hence its basicity decreases. no such resonance is seen in cyclohexyl amine, and the lone pair is available to abstract protons and it is stronger base than aniline.
